研究了三电平电压源逆变器中正弦三角形PWM方案与空间矢量PWM方案之间的内在联系。结果表明，在正弦三角形调制的情况下，通过适当选择共模注入，或者在空间矢量调制的情况下，通过在等效冗余开关状态下的停留时间，这两种方案可以等效地发挥作用。仿真和测量结果表明，理解这些关系可以导致更有效和灵活的三电平调制器，具有理想的或最佳的性能。
This paper studies the inherent relations between sine-triangle and space vector PWM schemes for three-level voltage source inverters. It is shown that the two schemes can function equivalently through proper selection of common mode injections in the case of sine-triangle modulation, or dwell times in equivalent redundant switching states in the case of space vector modulation. Simulation and measurement results illustrate that understanding of these relations can lead to a more efficient and flexible three-level modulator with desired or optimal performance.
